Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

optimize-gpt-6-astra-prompts scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 141 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Optimize GPT-6 Astra Prompts

Turn rough ideas and existing prompt stacks into copy-ready GPT-6 Astra prompts. Preserve the user's intent and hard constraints, ask for genuinely blocking information, and apply Astra-specific mitigations only where the task or observed behavior requires them.

Use the official basis

Read references/official-guidance.md when model-specific rationale, API-setting guidance, migration notes, or the longer checklist is needed. Treat its URLs as canonical sources and its prose as a dated summary. Fetch the live OpenAI pages before making claims about the current model alias, parameters, availability, or other facts that may change.

For cleaning repository Skills, AGENTS.md, or Sol-era coding-agent scaffolding (wrong skill loads, full-repo pre-reads, over-testing, early stops), use $audit-gpt-6-astra-skills instead of stuffing harness cleanup into a prompt rewrite. That skill follows Rethinking skills and prompts for GPT-6 Astra.

Follow the workflow

1. Capture the prompt contract

Identify the following from the user's message, pasted prompt, or referenced file:

  • intended user-visible outcome;
  • inputs and context the model will receive;
  • hard constraints and facts to preserve;
  • required output shape, audience, and language;
  • evidence, tool use, or validation needed for success;
  • side effects the model may take and actions that require approval;
  • autonomy level: when to ask, when to persist, and when approval is the final step;
  • fallback or stopping behavior when required information is unavailable.

Treat these as diagnostic dimensions, not mandatory sections. Keep a simple rewriting prompt simple.

If the user supplies a layered prompt stack, preserve the separation between system, developer, user, and tool-description content. Do not silently move instructions between trust levels.

2. Apply the clarity gate

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
